Action to disable the checkout button [#2422839]

I have simple rule based on address comparison designed to apply a flat shipping rate and change the shipping page properties to advise the buyer that an manual shipping quote needs to be requested. (The business logic being that the shop owner would manually update the flat rate shipping amount and then the buyer would resume checkout.)

I know the rule is firing because of a the inclusion of a status message, but the 'Change page property' actions are not being triggered. Tested with Commerce Kickstart 7.x-2.20 (Rules 7.x-2.7) (Commerce Rules Extra 7.x-2.1)

Any suggestions about what I am doing wrong?

Here is the rule

{ "commerce_shipping_service_subject_to_quotation" : {
    "LABEL" : "Shipping rate subject to quotation",
    "PLUGIN" : "rule",
    "OWNER" : "rules",
    "REQUIRES" : [ "commerce_order", "commerce_rules_extra", "rules" ],
    "USES VARIABLES" : { "commerce_order" : { "label" : "Order", "type" : "commerce_order" } },
    "IF" : [
      { "commerce_order_compare_address" : {
          "commerce_order" : [ "commerce_order" ],
          "address_field" : "commerce_customer_shipping|commerce_customer_address",
          "address_component" : "country",
          "value" : "DE"
        }
      }
    ],
    "DO" : [
      { "commerce_rules_extra_change_page" : {
          "page_id" : "shipping",
          "help" : "Shipping Quote Required: Your order requires a shipping quote, please await an email with a shipping quote and check out afterwards.",
          "submit_value" : "Shipping Quote Required"
        }
      },
      { "drupal_message" : { "message" : "Shipping quote required" } }
    ]
  }
}

And here is the log

Quick question. So the shipping address to trigger this is Germany?

Next question. What is the weight of the rule?

I need to get some Documentation started on D.O about this module and Rules in general with Drupal Commerce. I have found that rule weight is very, very important with a shopping cart checkout.

If you took the default weight of 0 I would suggest trying to bump that up to a higher number, like 10. There are a lot of rules that are weight 0 that come default with Drupal Commerce. So much so that often some rules will not process if they aren't set to process later (higher number).

Yes, DE=Germany, although I was only using this for testing purposes and actually it's not a rule but a (shipping rate) component and from what I can see there is no weight value for components.

To be honest, I am flapping about a bit with this. My use case is for buyers located at a shipping address for where there is no shipping rate available and for where the shop owner would need to manually quote/add a shipping rate to an order before the buyer completed checkout. The trouble is, there does not seem to be a suitable way of preventing checkout before a shipping rate has been added to the order.

I was hoping that the checkout page properties could be changed somehow to ask buyers not to checkout, but this is not a good solution really.

Ideally what is needed is for the checkout button (continue to next step) to be disabled based on order status. This way a rule could change the order status to (say) 'request for shipping quotation' when the address conditions have been met and once the status has been changed to (say) 'shipping rate quoted' the checkout button could be made to display again. A few emails fly about and when the buyer returns to their cart they see a quoted shipping rate.

Would it be too much too ask for an additional action for this fine module? Disable/enable checkout submit button?

@MrPaulDriver I think that would be possible to make an action that disabled the button. At the moment I am also in development of another module (CDN optimized JW Player) so I my time isn't as much as normal. But I will start looking into it. I think it might be fairly easy by doing a hook_form_alter() on the checkout form to remove the button to checkout.
